Question

Eli5…Why do balloons make sound when they pop?

In: 1

Answer 1

Sound is really pressure waves in air,
which means that the molecules are denser in some regions of the air than others, and that these high-pressure regions move as a wave. Your ears detect such waves. A balloon collapses when the internal pressure becomes to great and the internal pressure then starts a wave that moves outward.
